NS_E_OPEN_CONTAINING_FOLDER_FAILED
Read this as a state transition
NS_E_OPEN_CONTAINING_FOLDER_FAILED means Windows Media Player could not ask the shell to open the folder containing the selected item.
The result comes from the library-to-shell handoff after resolving the item path. A representative case is a library entry points to a moved file whose parent directory no longer exists.
Evidence to preserve
original library URL, resolved local path, file and parent existence, shell execution result, access rights, and whether the item is remote.
Record before the object changes
Test one hypothesis at a time
- Record and verify: original library URL, resolved local path, file and parent existence, shell execution result, access rights, and whether the item is remote.
- Run the controlled comparison: open the resolved parent directory directly under the same user and compare with a known local item.

Here, file-open playback errors concern reading media; this code concerns opening its containing folder in the shell.
Confirm the correction
For this occurrence, repair the library path or parent folder and handle non-file URLs without invoking the shell.
